The Eisenhower dollar was a one dollar coin issued by the United States Mint from 1971 to 1978. It was the first coin of that denomination issued by the Mint since the Peace dollar series ended in 1935. The coin depicts President Dwight D. Eisenhower on the obverse, and a stylized image honoring the 1969 Apollo 11 Moon mission on the reverse, with both sides designed by Frank Gasparro (the reverse is based on the Apollo 11 mission patch designed by astronaut Michael Collins). It is the only large size U.S. dollar coin whose circulation strikes contained no silver. In 1965, because of rises in bullion prices, the Mint began to strike copper nickel clad coins instead of silver. No dollar coins had been issued in thirty years, but beginning in 1969, legislators sought to reintroduce a dollar coin into commerce. After Eisenhower died that March, there were a number of proposals to honor him with the new coin. While these bills generally commanded wide support, enactment was delayed by a dispute over whether the new coin should be in base metal or 40% silver. In 1970, a compromise was reached to strike the Eisenhower dollar in base metal for circulation, and in 40% silver as a collectible. President Richard Nixon, who had served as vice president under Eisenhower, signed legislation authorizing mintage of the new coin on December 31, 1970. Although the collector’s pieces sold well, the new dollars failed to circulate to any degree, except in and around Nevada casinos, where they took the place of privately issued tokens. There are no dollars dated 1975, coins from that year and from 1976 bear a double date 1776–1976, and a special reverse by Dennis R. Williams in honor of the bicentennial of American independence. Beginning in 1977, the Mint sought to replace the Eisenhower dollar with a smaller sized piece.
Type 1 and Type 2
On the reverse side the lettering was modified. Type 1 has thicker lettering than Type 2.
It is easy to see the difference between Type 1 and Type 2 lettering.
